MILK-CAN-VENTILATIN G DEVICE.

Specification of Letters Patent.

Patented July 1, 1913.

Application filed August 5, 1,912. Serial No. 713,338.

. To all whom it may concern:

Y to` overcome these `objections.

Be it known that I, EMMOT O. DoscH, a citizen of the United States, residing at Cashton, county of Monroe, and State of Wisconsin, have invented certain new and useful Improvements in Milk-Can-Venti'lating Devices, of .which the following is a specification.

This invention relates to Ventilating devices and is especially adapted to' be used in connection with milk or cream receptacles;

A comlnon objection to the present method of shipping or packing milk or cream inf close or unventilated receptacles, is that the contents by not being supplied with fresh air, become rancid and useless in a short time. This consequently shortens the shipping radius' of perishable goods of such character, and also permits the milk` and cream to retain the animal flavor'common thereto, and of which it would be relieved if supplied by fresh air. Should the'lids or covers of the receptacles be left o', in an effort to overcome these objections, the contents is liable to become infected by flies and other insects, dust and dirt, and is also accessible to small animals such as cats, dogs,

etc.

It is the principal object of my invention A further object of Vmy invention is to provide a dev'ice for the purposek mentioned which is sim le in construction and yet thoroughly e cient, and which, while allowing freenassage of air to the contents of the receptacle, will prevent the access of animals or insects thereto.

My device may be made in severalsizes to fit `upon the receptacles of different dimensions, and different types, however, the same basic principle is employed in the various changed forms and the manner of application remains the same.

ln carrying out my invention l resort to the use of a ventilator which is hollowVand preferably cylindrical \in shape, or ofa shape to correspond to that of the mouth of the receptacle, and which is adapted to fit into or upon the top of aymilk or cream re` ceptacle. The lower portion of the ventilator extends suitable distance into the .niouth of the receptacle to insure its stability, and the outer or exposed surface of the *cyhnder is provided around its periphery with a plurality of perforations. To' preivent the ventilator from extending too far into the receptacle, a stop is provided upon the exterior of the cylinder to engage the mouth of the vessel. The upper end of the ventilator is designed to accommodate the cap or top of the receptacle to which it is applied and its upper edge is' therefore of a construction similar to that of the mouth of the receptacle itself. The perfor-ations i1r'the cylinder, While being of a size small enough to exclude insects and the like, allow for the free passage of air intoand out of the vessel.` The cover .of the receptacle, being positioned upon the upper end of the ventilator, prevents insects or other vermin from entering through the top.

In. the drawings forming a part of this specification, Figure l is a vertical section of a Ventilating device embodying my invention and illustrating the same in theform used upon large cans such as are employed in shipping milk, the mouth of the can and the cover being also illustrated. Fig. 2 is a similar view illustrating the device as preferably constructed for use in conjunction with the usual milk .delivery bottle, the mouth of the `bottle beingshown in section. Fig.8 is a plan View 0f the device illustrated in Fig. 2, and, Fig. 4 is a modified form of the device.

Referring now to Fig.y 1 of the drawings, the upper end of a milk can of the usual well known construction is illustrated at l, and is provided with a neck or mouth 2, the latter being flanged at its upper end in the usual manner lat 3. My iniproied ventilator comprises a hollow cylinder l, formed preferably of sheet metal, being at its upper/end of a diameter vequal to that ,ofthe mouth of the receptacle, while atits lower end the cylinder is reduced in diameter as at 5 to fit snugly into the mouth of the receptacle. The upper edge of the cylindert is preferably flared as at (i, to correspond-to theflare or flange 3' of the receptacle, and said upper end is adapted to receive the rover T of the receptacle.

waited from extending too 'far into "Flic cylinder terior 'of the receptacle, and the animal heat allowed to escape Without danger of dirt, insects, etc., being admitted, and the presence of the cap or cover of the milk can upon the top of the ventilator protects the milk or other contents against small animals.

In Fig. 2 of the drawings I have illustrated my invention in connection with the ordinary milk bottle, and in which there is but slight change over the form shown in Fig. 1, except that it is reduced in size to be adapted for use upon the ordinary milk bottle. The cylinder 4 in this form is of the same diameter throughout its entire length, being provided with a peripheral groove l() intermediate its ends to limit its inward movement when placed in position within the mouth of 'the receptacle, and above the perforations 9 the upper end is formed with a seat 11 for the usual paper cap 12 of the bottle.

Fig. 4 illustrates a further modication of the form shown in Fig. 2, and in which wire mesh is employed in lieu of the perforations in the periphery of the cylinder.,

In this form a cuff or band 13 is employed and is of a diameter to snugly fit into the mouth of the milk' bottle. Soldered or otherwise secured to the outer upper edge of the cuff 13 is a band of wire mesh 14, which is of a width sufiicient to admit proper ventilation. Secured to the top of the wire mesh and to the outer edges thereotl is a metallic band 15. This band'cxtends a short distance above the upper edge of the wire mesh and is adapted to confine within its inner circumference the paper cap'12 of the milk bottle. A metallic band 16 may be secured to the inside of the Wire mesh and in such position that its upper edge is in the same plane as that of the upper edge of the wire 14, so as to enlarge the seat for the paper cap 12. The lower end of the wire mesh 14, being soldered or secured to the outside of the cufi1 13, forms an annular shoulder to preventthe ventilator from extending too far into the bottle. v

It will be obvious from eis description takei in connection with the drawings that a can ar bottle ventilator constructed in aecordanee therewith will be of extreme benefit to those interested inl milk and cream shipping, in view of the fact that the ventilaters are inexpensive, simple in construe'- tion, and may be easily and quickly applied to a can or bottle. The content-s of the receptacle is at all times exposed to a current of fresh air, and the danger of animals or insects gaining access thereto is reduced to a minimum. The ventilators, by their simple construction are readily renovated, and their use upon milk or cream receptacles relieves the contents of the animal flavor common to milk shipped in air tight vessels, and also keeps the contents sweeter a greater length of time.

Having thus described my invention, what I claim and desire to secure by Letters Patent is 1. A ventilator of the class described comprising a tubular member open at both ends, one end of said member being adapted to be inserted into the mouth of a vessel, the other end of said tubular member being adapted to receive the cover of said-vessel, and the walls of said tubular member being provided with a foraminated portion, substantially as described.

2. A ventilator of the class described comprising'a tubular member open at both ends, one end of said member being adapted to be inserted into the mouth of a vessel, the

other end of said tubular member bein adapted to receive the cover of said vesse stop for limiting lthe inward movement of the said tubular member into the vessel, and the Walls of said tubular member being provided with a foraminated portion, substantially as described.

8. A ventilator of the class described comprising a tubular member open at both ends,

lprising a tubular member open at both ends,

oneend of said member beingadaptedto be inserted into the. mouth of a vessel, the other end of said tubular member being enlarged to receive thev cover of said vessel, and the walls of said tubular member being provided with a oraminated portion, substantially as described.

5. A ventilator of the class described comprising a tubular member open at both ends, one end of said member being reduced in size to fit within the mouth of a receptacle, the other end of said tubular member being of the same size and construction as the mouth of said rece tacle to receive the cover name to this specification inthe presence of thereof, a stop for miting the inward movetwo subscribing wltnesses. ment of the ysaid tubular member into the vessel, and the exposed walls of said tubular f EMMOT O BOSCH' member being foraminated, substantially as Witnesses: described.y WM.
